Linear algebraic formula
The basic formula of linear algebra is:? (ab)^t=(b^t)(a^t),(ab)^(- 1)=[b^(- 1)][a^(- 1)]。 Two vectors a? =? 【a 1,? a....? An] and b? =? [b 1,? B2, bn] is defined as:? Answer? B=a 1b 1+a2b2+ ... one billion dollars.

Linear algebra is a branch of mathematics, and its research objects are vectors, vector spaces (or linear spaces), linear transformations and linear equations with finite dimensions. Vector space is an important subject in modern mathematics. Therefore, linear algebra is widely used in abstract algebra and functional analysis; Through analytic geometry, linear algebra can be expressed concretely. The theory of linear algebra has been extended to operator theory. Because the nonlinear model in scientific research can usually be approximated as a linear model, linear algebra is widely used in natural science and social science.
